SPECIFICATION forming part of Letters Patent N 0. 656,499, dated August21, 1960.

Application filed April 20, 1900.

T0 (0Z5 whom it nut I concern.-

Be it known that I, JONAS O. Bonita, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented new and useful Improvements in Stereoscopes, of which thefollowing is a specification.

My invention relates to stereoscopes, and more particularly to the kindin which a series of pictures can be successively brought into positionfor viewing through the lenses.

The object of my invention is to provide an apparatus of this characterwhich combines simplicity with efiiciency and beauty of design withusefulnessone inwhich the pictures will be secure in their frames, butat the same time may be easily removed and others substituted. Theseadvantages are accomplished by a novel arrangement and combination ofparts to be hereinafter fully described and claimed. a

In the drawings which accompany this specification and of which theyform a part, Figure 1 is a perspective of my machine. Fig. 2 is a sideview of the same with parts broken away. Fig. 3 is a central transversesection of the same. Fig. 4 is a front elevation of one of thepicture-holders, Fig. 5 is a modi-' fied form of cylinder-head which Imay use;

In the drawings like characters of reference denote like parts whereverthey occur.

My device consists of a cabinet A of convenient size and apicture-cylinder B, mounted in said cabinet. The cylinder B consists ofthe combination of stub-shafts 1, journaled in the sides of cabinet A,said shafts being provided with shoulders 2 to prevent wabbling andfitted at one end with an operatingknob, a cylinder 4- of light materialkeyed to shaft 1, cylinder-heads 5, fastened to the ends of saidcylinder by screws or otherwise, said cylinder-heads havingcorresponding perforations near their periphery, and picture-holders 7,mounted in perforations 6, said picture-holders consisting of two singleholders 8, formed integral with or mounted on member 9, with anintervening portion 10, member 9 having integral therewith cylindricalportions 11,which fit perforations 6. Aspring 12, provided with a coiledend 13, is mounted brought into position for viewing.

in cabinet A,with one end extending between Serial No. 13,609. (Nomodel.)

the single holders 8 and curved over so that the coiled end catches onthe portion 10 of one of the frames and holds itin position to beviewed. Cabinet A is formed of alower portion of ordinary constructionand a top portion consisting of sides 14, inclined ends 15 and 15, andhinged top 16. End piece 15 is inclined at an angle just sufl'lcient tomake it parallel to the plane of the picture in viewing position. Seatedin sockets in end piece 15 are lenses 17 for viewing the pictures, and

they are inclined so as to give the stereopticon I graphs, each pair ofpictures being alike.

The top is then closed and the knob turned in the direction of the arrowtill the picture desired comes in position with the end of the springholding it. It is then in a position parallel to the plane of the lensesand can be looked at as long as desired. When another is desired, theknob is turned farther, the spring releases the first one, and it fallsby gravity, making room for the second to be seen. In this manner anypicture can be As the pictures lean backward during the time they arebeing looked at all danger of the spring releasing its grip is obviated.

My device is also adapted to be used as a kinetoscope to show asuccession of pictures of a moving object. When used in this mannor, acontinuous series of pictures of the moving object is inserted inthepictureframes and the cylinder. rapidlyrevolved, while the picturesare viewed through the lenses.

I do not wish to be limited as to details of construction, as manychanges can be introduced without departing from the spirit of myinvention.

a casing, picture-frames mounted in pairs on common shafts journaled insaid cylinder,

and a curved spring arranged to extend between said pairs of frames andengage in succession said shafts to retard said frames and hold them inviewing position as the cylinder is revolved.

2. In a stereoscope, a cylinder, a support for said cylinder, a doublepicture frame mqunted on a shaft supported by said cylinder, said shaft,and a curved spring adapted to engage said shaft to retard said framesand retain them momentarily in viewing position.

In testimony whereof I have hereunto set my hand in presence of-twosubscribing wit- HGSSGS.
